Serrated Beach Pole with Fins, Sleeve and Rotation and Fixation Lever

ABSTRACT

This invention concerns a beach umbrella to which some modifications are applied and which are the object of this claim. This invention facilitates the task of placing the umbrella pole securely to the ground, with the minimum effort and the minimal waste of time.

TECHNICAL FIELD

THE USEFULNESS OF THIS INVENTION APPLIES MAINLY TO THE BEACH. AS AMATTER OF FACT, IF FOR INSTANCE, YOU INTEND TO ENSURE THE UMBRELLA'SSTABLE PLACEMENT AT THE BEACH, THE OPERATION WILL START WITH THEPLACEMENT OF THE POLE INTO THE SAND.

BACKGROUND ART

THIS OPERATION THOUGH TRIVIAL, MAY BE DIFFICULT, AS WITH TRADITIONALUMBRELLA POLES YOU WILL EITHER NEED GREAT ENERGY OR TO PUSH THE POLEDOWN OR TO MAKE A HOLE FIRST.

ANOTHER SMALL PROBLEM WHICH MAY OFTEN OCCUR WITH A BEACH UMBRELLA, WHENGOING TO THE BEACH, IS THAT THE ACTION OF THE WIND MAY EASILY PULL THEUMBRELLA OUT OF THE SAND. YOU MAY OFTEN HAVE SEEN BEACH UMBRELLAS FLYINGIN THE WIND CHASED BY THEIR OWNERS.

DISCLOUSER OF INVENTION THIS INVENTION SOLVES THESE PROBLEMS

BEARING IN MIND THAT A BEACH UMBRELLA IS MADE UP OF TWO SEPARATE PARTS,ONE IS FIXED TO THE GROUND, “THE POLE”, AND THE OTHER, THE UPPER PARTINCLUDING “THE CANOPY” IS FITTED ON THE LOWER ELEMENT AND CLAMPS FIRMLYON IT. (FIG. 1)

THE IDEA CONSISTS IN MODIFYING THE PART OF THE POLE FIXED TO THE GROUNDPROVIDING IT WITH 4 NEW PARTS, WHICH CORRESPOND TO THE CLAIMS OF THISINVENTION, LEAVING THE UPPER PART (THE CANOPY) UNCHANGED. THE WHOLEDESIGN IS THE RESULT OF AN ACCURATE STUDY, EACH PART HAS BEEN OPTIMEZEDIN ORDER TO REQUIRE THE MINUM EFFORT AND THE MINIMAL WASTE OF TIMETOGETHER WITH THE MAXIMUM RESULT, THUS OBTAINING A VERY COMPETITIVEPRODUCT IN TERMS OF USEFULNESS AND COST.

BRIEF DESCRIPTION OF DRAWINGS

THE IDEA CONSISTS IN:

APPLYING A SERRATED AND FINNED ELEMENT TO THE LOWER PART OF THE BEACHUMBRELLA POLE, LEAVING THE INTERNAL PART OF THE POLE HOLLOW SO THAT THESAND CAN FLOW. THE CENTRAL HOLE IN THE LOWER PART OF THE POLE WILL HAVEA HEIGHT OF ABOUT 20 mm AND AN INNER DIAMETER ABOUT 1 mm NARROWER, SOTHAT THE SAND CAN FLOW WITHOUT ANY FRICTION, THIS WILL ALLOW THE SAND TOPENETRATE WITH REDUCED FRICTION.

THIS ELEMENT WILL ALSO BE EQUIPPED WITH TWO SIDE FINS, IN THE SHAPE OFTWO SMALL PROPELLERS, TILTED ABOUT 20° WITH RESPECT TO THE VERTICALAXIS, PLACED ON THE EXTERNAL PART IMMEDIATELY ABOVE THE SERRATEDELEMENT. THE FINS WILL HAVE A THINNER FRONT PART IN THE SHAPE OF APROPELLER, THIS DEVICE REQUIRES MINUM PENETRATION EFFORT WITH MAXIMUMRESISTENCE. FINALLY, TWO SMALL “TEETH” WILL HELP SAND PERFORATION.(FIGS. 2A 2B 2C 2D).

PERFORMING THE FUNCTION VIA A LEVER POSITIONED IN THE UPPER PART OF THEPOLE AND EQUIPPED WITH A ROTARY KNOB WHICH HAS THE DOUBLE PURPOSE OFENABLING THE ROTATION OF THE POLE FOR ITS SCREWING AND SUBSEQUENTLY THELOCKING OF THE UPPER PART OF THE UMBRELLA. THE CLAIM CONCERNS THE SYSTEMADOPTED FOR THE OPERATION OF THIS ELEMENT, SINCE IN ORDER TO PERFORM AROTARY EFFORT, WITHOUT CREATING EITHER BREAKING OR SAGGING, THERESISTENCE IS SUPPORTED BY THE SIDE OF THE POLE OPPOSITE THE HINGE TOWHICH THE LEVER IS FIXED.

AS A MATTER OF FACT MAKING N° 2 LONGITUDINAL SLITS IN THE POLE (FIG. 3),THE ROTATION LEVER, IN THE WORKING POSITION OF PENETRATION WILL ACHIEVEEXCELLENT WORKING RESISTENCE (FIG. 4A FIG. 4B).

EQUIPPING THE TOP PART OF THE POLE, THE PART IMMEDIATELY BELOW THELEVER, WITH A SLEEVE FREE TO ROTATE AROUND THE POLE, WITH A GRIPPINGFUNCTION AT THE TIME OF ROTATION, DURING THE PENETRATION OF THE POLEITSELF. THIS WILL ALLOW A FREE ROTATION OF THE SLEEVE, IT WILL ALSOFACILITATE ITS HOLDING DURING THE FREE ROTATION WHEN PLACING THE POLE.(FIG. 5)

BEST MODE FOR CARRYNG OUT THE INVENTION

PLACEMENT ASSEMBLY OF THE BEACH UMBRELLA:

USE THE ROTATION AND FIXING LEVER, PLACE IT IN THE WORKING POSITION(FIG. 4A FIG. 4B) AND HOLD THE SLEEVE WITH THE OTHER HAND (FIG. 5)PERFORM A ROTATION ENABLING THE PENETRATION OF THE POLE INTO THE SAND.

PLACEMENT WILL BE VERY FAST

SET THE LEVER IN THE OPEN POSITION (FIG. 6A), INSERT THE TOP PART OF THEUMBRELLA AND SET THE LEVER IN THE LOCKING POSITION (FIG. 6B) THE BEACHUMBRELLA WILL BE FIRMLY ANCHORED TO THE GROUND.

WHEN REMOVING THE UMBRELLA, THE OPERATION WILL BE EXACTLY THE SAMEEXECPT THAT THE ROTATION, OF COURSE, MUST BE PERFORMED IN THE OPPOSITEDIRECTION.

WHEN PLACING THE UMBRELLA ON DIFFERENT SOILS THE SAME OPERATION MUST BEPERFORMED.

THIS INVENTION IS VALUABLE BECAUSE THE VARIANTS OF THE UMBRELLA ARE VERYLOW COST.

IT GREATLY FACILITATES PLACEMENT OPERATIONS ESPECIALLY FOR THE ELDERLY,LADIES AND CHILDREN.

IT STRONGLY OPPOSES THE ACTION OF THE WIND SINCE THE TWO LATERAL FINSINCLUDED IN THE LOWER END OF THE POLE PREVENT ITS PULLING OUT. SO THEPOLE WILL REMAIN FIRMLY ANCHORED TO THE GROUND.
